21,978 PointsMovie Ratings Question Confusing
I'm really confused why this doesn't work.
SELECT
SUM(rating) AS starman_total_ratings
FROM reviews
WHERE id=6;
Or this
SELECT
SUM(rating) AS starman_total_ratings
FROM reviews
GROUP BY movie_id
HAVING id = 6;
I feel like the wording is ambiguous.

21,978 PointsOh, I got it.
The instructions say that the reviews columns include both an id, and movie_id column.
It then states: "starman has an 'id' of 6 Immediately after it states: "Movie ids are found in the movie_id column."
So instead of simply writing "starman has a movie_id of 6" he has actually misstated that starman has an id of 6, and we have no information on the movie_id of starman.
We are to assume with no knowledge that the instructor meant movie_id, when he actually said id -- and there are two distinct columns.
